+The view assumes either a Gimbal Camera (rotation,translation,distance)
+or Vector Camera (eye,center/target) is being used. See Camera.h. The
+cameras are not kept in sync.

+QGLView only uses GimbalCamera while OffscreenView can use either one.
+Some actions (showCrossHairs) only work properly on Gimbal Camera.
